There is a fetish for technology that sometimes we are not aware of. On average there might be less accidents, but if specific accidents were preventable and now they happen, people will sue. And who will take the blame? The day the company takes the blame is the day self-driving exists IMO.

A faulty break pad or an engine doesn’t take decisions that might endanger people. Self-driving cars do. They might also get hacked pretty thoroughly.

For the same reason, I’d probably never buy a home robot with more capabilities then a vacuum cleaner.
